One thing my ex said to me when he was divorcing me was that he had been told “if it’s a fair settlement neither of us will feel like we’ve gotten everything we’ve wanted”. This was very true.

She wants to have these conversations with you because she wants to bully you into the settlement she wants. Never respond to her requests - just say “I’ll discuss that with my attorney”. Just that: “ I’ll discuss that with my attorney”. Do not agree to ANYTHING. And remind her that two households cannot live as cheaply as one, so neither of you can expect the same lifestyle after divorce that you have now.

Btw - I just had a random thought about her statement that she makes as much as you - could she be lying? Do you file your taxes jointly, have you seen proof that she’s earning that much? Seems unlikely that it would be a lie, but if it was, might explain some of her freaking out about finances.
